1
00:00:04,120 --> 00:00:07,200
NARRATOR: Botswana,
a jewel in Africa's crown.

2
00:00:09,680 --> 00:00:11,400
But its beauty is deceptive.

3
00:00:13,920 --> 00:00:16,280
Out here, life is cut-throat.

4
00:00:19,040 --> 00:00:20,800
There is safety in numbers.

5
00:00:21,360 --> 00:00:25,360
Being in a gang can improve
your chances of survival.

6
00:00:28,920 --> 00:00:30,560
But gang life does have its dangers.

7
00:00:32,560 --> 00:00:35,960
Joining a posse
and keeping your place in it,

8
00:00:37,320 --> 00:00:38,600
is a matter of life...

9
00:00:40,800 --> 00:00:42,040
or death.

10
00:00:52,880 --> 00:00:56,880
In the grasslands of Botswana,
mobs rule.

11
00:01:09,160 --> 00:01:11,280
And of all the gangs here,

12
00:01:11,360 --> 00:01:13,560
it's the lions who reign supreme.

13
00:01:18,280 --> 00:01:21,680
A single lioness is a skillful hunter.

14
00:01:23,360 --> 00:01:25,800
More than 200 pounds of muscle.

15
00:01:31,200 --> 00:01:34,960
(birds chirping)

16
00:01:54,240 --> 00:01:57,800
She's capable of tackling prey
twice her size,

17
00:02:00,480 --> 00:02:03,360
(grunts)

18
00:02:08,440 --> 00:02:12,480
But while a lioness on her own
may face resistance...

19
00:02:17,320 --> 00:02:19,720
when a pride works together,

20
00:02:19,800 --> 00:02:21,880
they can be unstoppable.

21
00:02:26,800 --> 00:02:32,440
(grunting)

22
00:02:35,760 --> 00:02:37,080
For lions,

23
00:02:37,720 --> 00:02:41,720
gang life makes you stronger, braver,

24
00:02:43,400 --> 00:02:44,560
safer.

25
00:02:49,520 --> 00:02:51,440
Africa's deadliest.

26
00:03:15,320 --> 00:03:17,160
(lion growls)

27
00:03:18,800 --> 00:03:23,160
Every gang that roams these badlands
has its own rules,

28
00:03:23,240 --> 00:03:25,840
its own strengths and weaknesses.

29
00:03:27,440 --> 00:03:29,960
But one thing holds true,

30
00:03:30,040 --> 00:03:31,880
in the fight for survival,

31
00:03:31,960 --> 00:03:35,560
gangs always come out on top.

32
00:03:50,720 --> 00:03:52,400
If you're part of a gang,

33
00:03:52,480 --> 00:03:56,040
you don't have to be big or strong to win.

34
00:03:58,160 --> 00:03:59,800
Small and wiry,

35
00:03:59,880 --> 00:04:04,480
wild dogs operate in tight-knit
family groups of 20 or more.

36
00:04:08,240 --> 00:04:11,200
With canine comrades always at their side,

37
00:04:11,280 --> 00:04:12,880
the dogs are fearless.

38
00:04:14,720 --> 00:04:17,960
They do everything together, playing,

39
00:04:18,520 --> 00:04:21,600
sleeping, raising young

40
00:04:22,880 --> 00:04:24,160
and hunting.

41
00:04:28,640 --> 00:04:31,880
This bond makes them the ultimate gang.

42
00:04:36,200 --> 00:04:40,360
Their combined speed,
endurance and agility

43
00:04:40,440 --> 00:04:42,920
make them a match for almost any animal,

44
00:04:43,680 --> 00:04:44,680
prey...

45
00:04:45,440 --> 00:04:46,800
or predator.

46
00:04:57,160 --> 00:05:00,840
One on one,
a leopard could easily kill a dog.

47
00:05:04,360 --> 00:05:08,200
But the dogs are bold and courageous
when they're with their pack.

48
00:05:13,880 --> 00:05:16,600
Sticking together gives them
the upper hand.

49
00:05:21,720 --> 00:05:23,840
This leopard knows he's outgunned.

50
00:05:23,920 --> 00:05:27,000
His only choice
is to stay out of harm's way.

51
00:05:35,960 --> 00:05:38,880
Eventually the pack's hunger
gets the better of them

52
00:05:40,480 --> 00:05:42,000
and the gang heads out

53
00:05:42,080 --> 00:05:44,400
in search of easier pickings.

54
00:05:50,960 --> 00:05:52,280
Warthogs!

55
00:05:54,760 --> 00:05:59,360
A big male warthog is six times heavier
than a wild dog

56
00:06:01,080 --> 00:06:04,120
and it's armed with razor sharp tusks

57
00:06:05,520 --> 00:06:07,920
but the pack shows no fear.

58
00:06:11,080 --> 00:06:14,120
The alpha male and female lead the chase,

59
00:06:14,200 --> 00:06:16,120
singling out a young victim.

60
00:06:20,960 --> 00:06:23,920
The dog's teamwork gives them
the advantage.

61
00:06:26,680 --> 00:06:28,280
They are endurance runners.

62
00:06:30,600 --> 00:06:33,640
The gang will chase the prey
until it's exhausted.

63
00:06:35,680 --> 00:06:37,720
Taking turns to lead the pursuit,

64
00:06:37,800 --> 00:06:41,280
the dogs can reach speeds
of up to 40 miles per hour.

65
00:06:46,040 --> 00:06:49,240
This young warthog's only hope
is to head for cover.

66
00:06:57,680 --> 00:06:58,720
Gone!

67
00:07:08,720 --> 00:07:10,840
The gang may not be able to see him,

68
00:07:14,240 --> 00:07:15,640
but they can smell him.

69
00:07:26,520 --> 00:07:28,960
Tracking the warthog's scent trail,

70
00:07:32,880 --> 00:07:36,240
it doesn't take the team long
to find his hideout.

71
00:07:43,080 --> 00:07:44,840
They take turns digging...

72
00:07:49,240 --> 00:07:51,280
(warthog squeals)

73
00:08:01,520 --> 00:08:05,080
(squealing)

74
00:08:07,880 --> 00:08:09,960
...until he's driven out into the open.

75
00:08:12,360 --> 00:08:15,240
(squealing continues)

76
00:08:16,560 --> 00:08:19,480
And the pack, still working as a team,

77
00:08:20,080 --> 00:08:21,400
eats him alive.

78
00:08:28,280 --> 00:08:29,760
For some predators,

79
00:08:29,840 --> 00:08:34,840
being in a gang means you can bypass
the time and effort of hunting altogether.

80
00:08:37,200 --> 00:08:40,680
Hyenas are one of Africa's
most notorious criminal mobs.

81
00:08:45,000 --> 00:08:48,160
A noisy clan
always has an eye out for opportunity.

82
00:08:51,640 --> 00:08:55,680
And this female-dominated posse
roams the grasslands.

83
00:09:03,160 --> 00:09:06,520
The smell of fresh blood
has them on alert.

84
00:09:10,360 --> 00:09:12,680
Three young lions have made a kill.

85
00:09:16,160 --> 00:09:19,000
The hyenas outnumber the hunters
two to one.

86
00:09:21,480 --> 00:09:24,240
The odds are stacked in their favor.

87
00:09:26,000 --> 00:09:28,080
Attacking from all sides,

88
00:09:30,560 --> 00:09:34,720
they drive the lions off the carcass
by sheer weight of numbers.

89
00:09:35,400 --> 00:09:37,320
And the king of beasts

90
00:09:37,400 --> 00:09:42,000
is reduced to nothing more
than a frightened cat up a tree.

91
00:09:43,240 --> 00:09:46,680
(hyenas laughing)

92
00:09:53,920 --> 00:09:55,120
The gang of thugs

93
00:09:55,200 --> 00:09:59,320
steals the young lion's hard-earned feast
from under his nose.

94
00:10:04,120 --> 00:10:08,880
For hyenas being part of a gang
is a ticket to an easy meal.

95
00:10:11,080 --> 00:10:13,800
Victorious they take the prize.

96
00:10:21,640 --> 00:10:24,840
Hyenas aren't the only girl gangs
on the savanna.

97
00:10:28,080 --> 00:10:31,400
Elephant herds are strictly females
and their calves only.

98
00:10:41,720 --> 00:10:44,480
Males leave the herd
when they reach adolescence

99
00:10:44,560 --> 00:10:46,360
and learn to fend for themselves.

100
00:10:51,280 --> 00:10:54,840
Mothers, daughters, sisters and aunts

101
00:10:54,920 --> 00:10:57,880
endlessly roam the savanna
for food and water.

102
00:10:59,760 --> 00:11:01,880
The leader of the herd is the matriarch...

103
00:11:03,760 --> 00:11:06,440
the oldest and wisest female

104
00:11:06,520 --> 00:11:09,200
with more than 40 years
of life experience.

105
00:11:12,360 --> 00:11:15,120
The herd follows wherever she leads

106
00:11:16,360 --> 00:11:19,480
and she will lead for as long as she can.

107
00:11:22,360 --> 00:11:25,960
There is no fighting here,
no struggle for dominance.

108
00:11:27,360 --> 00:11:30,840
The perfect place to grow and learn
the secrets of life

109
00:11:30,920 --> 00:11:33,680
in a complex and ever-changing world.

110
00:11:37,080 --> 00:11:38,920
With the protection of the herd,

111
00:11:39,000 --> 00:11:42,360
this calf gains the skills it needs
to survive here.

112
00:11:48,840 --> 00:11:50,920
But it still has much to learn.

113
00:11:53,880 --> 00:11:58,200
And there are hungry eyes
of other gangs everywhere.

114
00:12:00,960 --> 00:12:05,400
It's never safe for a baby to be alone
in the ganglands of Botswana.

115
00:12:09,960 --> 00:12:11,520
The hunters of the savanna

116
00:12:11,600 --> 00:12:14,360
are always on the lookout
for their next victim.

117
00:12:25,800 --> 00:12:27,920
And the weak and defenseless

118
00:12:28,360 --> 00:12:30,560
are top of their hit list.

119
00:12:48,120 --> 00:12:51,040
Luckily, when you're part of this gang,

120
00:12:51,120 --> 00:12:53,360
someone always has your back.

121
00:13:03,160 --> 00:13:06,120
Generations of experience
have taught these elephants

122
00:13:06,200 --> 00:13:08,560
how to deal with troublesome cats.

123
00:13:18,720 --> 00:13:23,800
(elephant trumpeting)

124
00:13:25,320 --> 00:13:29,200
This lioness will have to try her luck
elsewhere.

125
00:13:31,240 --> 00:13:33,400
The baby elephant is safe,

126
00:13:33,480 --> 00:13:36,320
thanks to the love and protection
of her herd.

127
00:13:41,880 --> 00:13:46,280
Rearing young is a vital part of gang life
for wild dogs too.

128
00:13:47,120 --> 00:13:50,840
(wild dogs squealing)

129
00:13:51,640 --> 00:13:53,800
The whole pack shares the burden

130
00:13:53,880 --> 00:13:56,960
of feeding and defending
the alpha pair's pups.

131
00:13:58,800 --> 00:14:02,480
Daily meals of regurgitated meat
help them grow fast.

132
00:14:03,200 --> 00:14:06,640
(squealing continues)

133
00:14:17,360 --> 00:14:20,480
By the time they're just three months old,

134
00:14:20,560 --> 00:14:22,680
they're ready to leave the den

135
00:14:22,760 --> 00:14:24,600
and learn to hunt.

136
00:14:49,960 --> 00:14:53,480
Now the benefits of this shared parenting
are clear...

137
00:14:56,280 --> 00:14:57,720
in a single stroke,

138
00:14:57,800 --> 00:15:01,680
they've doubled the size of their gang,
boosting the pack's power.

139
00:15:04,080 --> 00:15:07,080
(squealing)

140
00:15:10,240 --> 00:15:12,080
They may still be novices

141
00:15:12,160 --> 00:15:13,320
but with experience,

142
00:15:13,400 --> 00:15:16,960
they'll become valuable members
of this elite group.

143
00:15:23,240 --> 00:15:27,440
Ensuring the pack's survival
in this cut-throat gangland.

144
00:15:30,840 --> 00:15:32,360
(lion roaring)

145
00:15:32,440 --> 00:15:36,120
Wild dog gangs may thrive
on co-operation and sharing,

146
00:15:37,000 --> 00:15:40,720
but life in other animal gangs
is not so free and easy.

147
00:15:44,480 --> 00:15:46,000
In a lion pride,

148
00:15:46,080 --> 00:15:48,800
each individual must know their place

149
00:15:48,880 --> 00:15:50,600
or face the consequences.

150
00:15:53,400 --> 00:15:56,160
A strong male lion may rule the roost...

151
00:15:58,280 --> 00:16:01,120
but it's the lionesses
who do the hard work.

152
00:16:11,200 --> 00:16:12,600
They lead the hunts...

153
00:16:24,400 --> 00:16:27,080
and their skills are legendary.

154
00:16:30,760 --> 00:16:35,800
(squealing)

155
00:16:51,880 --> 00:16:54,360
But once the pride has brought
a victim down,

156
00:16:55,040 --> 00:16:56,520
it belongs to the king.

157
00:17:02,720 --> 00:17:06,000
He is responsible for defending the pride,

158
00:17:06,080 --> 00:17:07,880
for keeping his family safe.

159
00:17:14,920 --> 00:17:17,560
And eating first is his right.

160
00:17:22,840 --> 00:17:26,200
It's also his reward to mate
with all the females

161
00:17:26,280 --> 00:17:28,120
and expand his personal army.

162
00:17:30,200 --> 00:17:32,520
Under the control of their commander,

163
00:17:32,600 --> 00:17:35,880
the females
help look after each other's cubs.

164
00:17:39,120 --> 00:17:41,520
Giving them the best chance of survival.

165
00:17:46,720 --> 00:17:50,120
The pride male is the protector
of every cub here.

166
00:17:56,840 --> 00:17:59,160
His cubs are his legacy...

167
00:18:09,560 --> 00:18:13,000
and he will do whatever it takes
to keep them from danger.

168
00:18:19,320 --> 00:18:22,360
Even if they do get on his nerves
sometimes.

169
00:18:27,600 --> 00:18:30,560
If another male overthrows
the gang leader,

170
00:18:31,080 --> 00:18:33,080
he could kill all the cubs

171
00:18:33,160 --> 00:18:34,840
and mate with the lionesses,

172
00:18:36,520 --> 00:18:38,640
obliterating the king's blood line.

173
00:18:43,880 --> 00:18:47,280
So when this lioness
brings a handsome stranger home,

174
00:18:49,880 --> 00:18:52,520
the king knows there's trouble brewing.

175
00:19:00,600 --> 00:19:03,680
And he's out
for the trouble-maker's blood.

176
00:19:13,040 --> 00:19:16,080
The pride's lionesses
are the king's property.

177
00:19:17,840 --> 00:19:20,520
The interloper's flirtatious behavior

178
00:19:20,600 --> 00:19:23,520
is a direct challenge to him

179
00:19:23,600 --> 00:19:25,680
and the future of his pride.

180
00:19:50,600 --> 00:19:53,320
There's only one way to settle this.

181
00:20:01,680 --> 00:20:07,120
(growling)

182
00:20:10,560 --> 00:20:12,720
He will fight to the death...

183
00:20:19,440 --> 00:20:22,880
(growling continues)

184
00:20:26,320 --> 00:20:29,400
...and remind his female of the rules.

185
00:20:30,920 --> 00:20:32,960
The king's legacy is safe,

186
00:20:33,680 --> 00:20:34,800
for now!

187
00:20:42,720 --> 00:20:45,920
It's not just predators
who find strength in numbers.

188
00:20:49,600 --> 00:20:53,040
Guinea fowl form posses of up to 55,

189
00:20:53,120 --> 00:20:56,240
scouring the ground for insects and seeds.

190
00:21:00,000 --> 00:21:03,520
This puts them at risk of ambush.

191
00:21:09,240 --> 00:21:10,920
But when you live in a gang,

192
00:21:11,000 --> 00:21:13,200
there's always someone on look out.

193
00:21:19,040 --> 00:21:22,800
Constant 360-degree surveillance.

194
00:21:25,600 --> 00:21:29,640
Even the best-camouflaged hunter
struggles to go unnoticed.

195
00:21:35,720 --> 00:21:37,080
(shrieking)

196
00:21:37,160 --> 00:21:38,880
A deafening alarm call

197
00:21:42,120 --> 00:21:44,920
and the whole flock is alerted
to the danger,

198
00:21:46,080 --> 00:21:47,320
just in time.

199
00:21:52,240 --> 00:21:55,480
The guinea fowl wont stop calling
until the leopard is gone.

200
00:21:59,080 --> 00:22:01,320
Safety in numbers.

201
00:22:08,120 --> 00:22:10,200
Zebra and wildebeest also use

202
00:22:10,280 --> 00:22:13,200
sheer numbers for protection
against predators.

203
00:22:15,760 --> 00:22:19,960
By joining forces, they create
a super-gang of the grasslands.

204
00:22:23,880 --> 00:22:25,720
But with so many members,

205
00:22:25,800 --> 00:22:28,640
disharmony can breed amongst its ranks.

206
00:22:34,960 --> 00:22:37,080
When wildebeest calves are born,

207
00:22:37,160 --> 00:22:40,440
there's a shift in the mega gang's
peaceful relationship.

208
00:22:52,720 --> 00:22:54,920
The babies attract predators

209
00:22:55,000 --> 00:22:57,800
and put the zebras own survival at risk.

210
00:23:12,400 --> 00:23:16,200
(braying)

211
00:23:27,640 --> 00:23:31,120
This is not something
the zebra will tolerate.

212
00:23:45,280 --> 00:23:46,920
In a vicious turn,

213
00:23:47,000 --> 00:23:49,520
the gang up on the wildebeest calf.

214
00:23:51,600 --> 00:23:54,760
The alliance that once offered protection
has turned on them

215
00:23:55,360 --> 00:23:56,680
and is now...

216
00:23:57,360 --> 00:23:58,880
their greatest threat.

217
00:24:06,280 --> 00:24:08,120
In the heart of lion country,

218
00:24:08,200 --> 00:24:12,320
the zebra know babies are an easy meal
for the big cats.

219
00:24:17,680 --> 00:24:20,640
So high-risk members must be kicked out

220
00:24:20,720 --> 00:24:22,000
for the greater good.

221
00:24:31,840 --> 00:24:35,560
The zebra and wildebeest
super gang is shattered.

222
00:24:38,120 --> 00:24:41,120
Wildebeest babies must keep a low profile.

223
00:24:43,520 --> 00:24:48,040
This calf has learned the gang rules
the hard way.

224
00:24:48,600 --> 00:24:51,680
(braying)

225
00:24:55,440 --> 00:24:58,760
Babies are not all born equal
in animal gangs.

226
00:25:00,080 --> 00:25:03,000
Female hyenas breed in shared dens

227
00:25:03,080 --> 00:25:05,160
and raise a mob of cubs together,

228
00:25:06,520 --> 00:25:09,000
a new generation of clan members.

229
00:25:11,040 --> 00:25:13,760
But this is no democracy.

230
00:25:18,400 --> 00:25:19,840
It's a dictatorship.

231
00:25:20,720 --> 00:25:23,480
The clan is ruled
by a single dominant female.

232
00:25:25,160 --> 00:25:26,640
She demands respect

233
00:25:26,720 --> 00:25:28,600
and an established hierarchy

234
00:25:28,680 --> 00:25:30,840
means her followers know their place.

235
00:25:33,320 --> 00:25:36,200
She reigns
over a tyrannical pecking order.

236
00:25:44,480 --> 00:25:47,320
Her female cubs inherit her rank.

237
00:25:48,600 --> 00:25:50,480
It guarantees them the best food,

238
00:25:51,360 --> 00:25:52,680
the best mates

239
00:25:52,760 --> 00:25:54,960
and the best chance of success.

240
00:25:57,800 --> 00:26:01,800
Everyone else must fight
for their status in the clan,

241
00:26:03,400 --> 00:26:06,080
a struggle that starts
as soon as they're born.

242
00:26:13,000 --> 00:26:15,920
Males are destined
to be bottom of the heap,

243
00:26:16,920 --> 00:26:19,360
lower than the lowest ranking female.

244
00:26:23,400 --> 00:26:26,040
To be born female in a hyena clan,

245
00:26:26,120 --> 00:26:28,320
is to be born with the upper hand.

246
00:26:33,880 --> 00:26:36,280
When superiority isn't your birthright,

247
00:26:36,360 --> 00:26:38,440
you have to fight for dominance.

248
00:26:40,240 --> 00:26:41,680
In a wildebeest gang,

249
00:26:41,760 --> 00:26:44,640
once you've won the battle
for alpha male status,

250
00:26:44,720 --> 00:26:47,920
it's your prerogative
to mate with whoever you want.

251
00:26:51,680 --> 00:26:55,240
The dominant male
rules over a group of females.

252
00:26:58,280 --> 00:27:01,760
Any claim on them
will be seen as a challenge.

253
00:27:04,640 --> 00:27:08,720
Male wildebeest compete
to bolster their harem of females...

254
00:27:13,760 --> 00:27:17,080
and this rival male
is intent on seduction.

255
00:27:21,480 --> 00:27:24,640
His advances kick-off
a breeding territory war.

256
00:27:29,000 --> 00:27:32,520
The dominant male must fight
for his girl crew.

257
00:27:34,640 --> 00:27:37,400
His skull can absorb the forceful blows,

258
00:27:39,920 --> 00:27:42,360
but he risks breaking his horns.

259
00:27:43,440 --> 00:27:47,720
(braying)

260
00:27:48,280 --> 00:27:50,760
After this brief but vicious clash,

261
00:27:50,840 --> 00:27:54,000
the intruder is chased out
of the winner's herd.

262
00:28:03,440 --> 00:28:05,520
In the blistering heat of the afternoon,

263
00:28:06,080 --> 00:28:08,560
gangs big and small take a rest.

264
00:28:10,360 --> 00:28:11,760
For banded mongoose,

265
00:28:11,840 --> 00:28:15,600
ganging up together at nap time
is key to survival.

266
00:28:18,160 --> 00:28:22,360
Because not everyone takes time out
from the midday sun.

267
00:28:25,640 --> 00:28:27,560
With one strike of its claws,

268
00:28:27,640 --> 00:28:31,560
a martial eagle could easily snatch
a sleeping mongoose.

269
00:28:35,200 --> 00:28:37,000
But in their mongoose mob,

270
00:28:37,080 --> 00:28:38,920
they're not to be messed with.

271
00:28:45,960 --> 00:28:47,800
Their bravado seems to work.

272
00:28:51,960 --> 00:28:53,560
They don't run scared

273
00:28:53,640 --> 00:28:57,840
but instead bunch together to pester
Africa's largest eagle.

274
00:28:59,000 --> 00:29:02,480
(squeaking)

275
00:29:12,960 --> 00:29:16,760
This apex predator's plan of attack
is thwarted.

276
00:29:21,680 --> 00:29:23,920
However, small and squeaky you are,

277
00:29:24,000 --> 00:29:26,600
there's always victory in a union.

278
00:29:30,520 --> 00:29:33,200
When two powerful gangs collide,

279
00:29:33,280 --> 00:29:35,680
the outcome is impossible to predict.

280
00:29:40,280 --> 00:29:44,600
This is one of Africa's
mightiest animal armies.

281
00:29:46,320 --> 00:29:49,520
A herd of buffalo, thousands strong.

282
00:29:54,000 --> 00:29:56,320
This huge assembly of lethal muscle

283
00:29:56,400 --> 00:29:58,600
is enough to put off most predators.

284
00:30:01,080 --> 00:30:02,760
But not lions,

285
00:30:03,320 --> 00:30:06,320
one of Africa's deadliest gang of killers.

286
00:30:12,840 --> 00:30:16,120
They know this fearsome army
has a weakness.

287
00:30:20,520 --> 00:30:23,560
Amongst the seasoned warriors
are new calves,

288
00:30:23,640 --> 00:30:26,400
inexperienced and vulnerable.

289
00:30:34,400 --> 00:30:36,600
(bellowing)

290
00:30:38,920 --> 00:30:40,280
Working together,

291
00:30:40,360 --> 00:30:43,800
this is the weakness
the lions will exploit.

292
00:30:46,600 --> 00:30:48,760
The pride shadows the herd,

293
00:30:48,840 --> 00:30:52,440
watching, waiting for the perfect moment.

294
00:31:10,200 --> 00:31:14,240
As dusk falls,
the lion gangs attacks from all sides.

295
00:31:27,480 --> 00:31:29,120
In the panic and confusion,

296
00:31:29,200 --> 00:31:33,000
a calf is isolated
and the pride is right there.

297
00:31:38,680 --> 00:31:41,920
But this ambush is far from over.

298
00:31:45,960 --> 00:31:49,320
Never underestimate the power
of a protective mother.

299
00:31:54,240 --> 00:31:58,920
(bellowing)

300
00:32:06,560 --> 00:32:09,600
Confronted by a tone of furious muscle,

301
00:32:09,680 --> 00:32:11,680
the lion gang retreats.

302
00:32:17,080 --> 00:32:19,120
She will kill them if she can.

303
00:32:23,080 --> 00:32:25,880
The rest of the herd returns
to back her up.

304
00:32:28,640 --> 00:32:31,720
What may have been an easy hunt
for the lions

305
00:32:31,800 --> 00:32:35,840
has turned into a battle
between two Goliath gangs.

306
00:32:37,480 --> 00:32:41,520
The buffalo are bigger and their horns
could fatally injure a lion.

307
00:32:44,920 --> 00:32:47,240
Outnumbered and outweighed,

308
00:32:47,320 --> 00:32:50,640
the pride realizes it's time to go.

309
00:32:54,160 --> 00:32:55,760
The buffalo have won,

310
00:32:55,840 --> 00:32:59,200
proving the power behind gang loyalty.

311
00:33:11,680 --> 00:33:13,480
As the dry season takes hold,

312
00:33:14,960 --> 00:33:19,120
red-billed quelea arrive in their hundreds
of thousands to breed.

313
00:33:27,000 --> 00:33:31,520
Immense flocks weave nests of dry grass
in the acacia trees.

314
00:33:31,880 --> 00:33:34,720
(chirping)

315
00:33:36,080 --> 00:33:38,960
High above the ground and surrounded
by thorns,

316
00:33:39,040 --> 00:33:41,040
the nests are safe from predators.

317
00:33:44,800 --> 00:33:47,560
But to find food
for their ravenous chicks,

318
00:33:47,640 --> 00:33:50,440
the quelea must leave
the cover of the the trees

319
00:33:50,520 --> 00:33:52,040
and head into the open...

320
00:33:53,560 --> 00:33:57,000
(chirping continues)

321
00:33:57,480 --> 00:33:59,560
...where danger is waiting.

322
00:34:01,640 --> 00:34:04,840
Any quelea leaving
the safety of the trees alone

323
00:34:04,920 --> 00:34:07,280
would be spotted and taken instantly.

324
00:34:09,080 --> 00:34:12,360
So the quelea work together
to cheat death.

325
00:34:14,440 --> 00:34:17,880
Hundreds of thousands of them
take flight simultaneously.

326
00:34:23,200 --> 00:34:26,280
The visual chaos of almost
a million wings beating

327
00:34:26,360 --> 00:34:29,280
can dazzle even the most eagle-eyed.

328
00:34:32,320 --> 00:34:34,120
This is a numbers game.

329
00:34:41,600 --> 00:34:43,920
The more quelea there are in the gang,

330
00:34:44,000 --> 00:34:47,280
the smaller the chance
of any individual being caught.

331
00:34:56,520 --> 00:34:58,320
For every quelea taken,

332
00:34:58,400 --> 00:35:02,120
countless thousands more
live to fly another day.

333
00:35:14,760 --> 00:35:16,160
If your gang is big enough,

334
00:35:16,760 --> 00:35:19,680
you don't always need violence
to get what you want.

335
00:35:28,440 --> 00:35:31,920
As a pack of wild dogs
devours a kudu carcass,

336
00:35:32,000 --> 00:35:34,960
vultures are drawn in from all sides.

337
00:35:38,400 --> 00:35:39,760
Riding the thermals,

338
00:35:39,840 --> 00:35:43,120
they can spot a kill from over a mile
up in the air.

339
00:35:53,760 --> 00:35:56,680
For them, it's just a waiting game.

340
00:36:08,120 --> 00:36:11,160
The dogs charge, trying to drive them off.

341
00:36:13,480 --> 00:36:16,040
(vultures screaming)

342
00:36:25,840 --> 00:36:27,840
But this feathered flock is huge

343
00:36:27,920 --> 00:36:31,120
and more members are cruising in
from far and wide.

344
00:36:34,600 --> 00:36:36,760
The dogs are bullied into leaving.

345
00:36:44,960 --> 00:36:47,800
The vultures feast unchallenged.

346
00:36:51,200 --> 00:36:54,240
All the rewards for so little effort.

347
00:36:59,720 --> 00:37:02,120
If gang life makes for an easy living,

348
00:37:02,480 --> 00:37:05,200
being an outcast can be a death sentence.

349
00:37:07,840 --> 00:37:10,760
Bull elephants are shunned
from the maternal herd

350
00:37:10,840 --> 00:37:12,480
once they become adolescents.

351
00:37:17,560 --> 00:37:20,000
They often lead a solitary life.

352
00:37:22,320 --> 00:37:24,400
Even though they might be big,

353
00:37:24,480 --> 00:37:25,920
they're still vulnerable.

354
00:37:29,520 --> 00:37:33,520
And lessons for life as a loner
come thick and fast.

355
00:37:36,040 --> 00:37:38,840
On their own
they're still targets for attack.

356
00:37:46,520 --> 00:37:48,280
So they sometimes buddy up

357
00:37:48,360 --> 00:37:51,720
with other bachelor bulls
to build small gangs.

358
00:37:54,640 --> 00:37:57,320
Banding together to find food and drink.

359
00:38:09,440 --> 00:38:12,560
These mini gangs
are ideal training grounds

360
00:38:12,640 --> 00:38:15,160
where elephants gain the skills they need.

361
00:38:18,400 --> 00:38:20,680
Sparring to build up their strength

362
00:38:21,600 --> 00:38:23,720
and learning the rules of adulthood.

363
00:38:25,280 --> 00:38:28,600
Everything they need to become
a successful male.

364
00:38:41,840 --> 00:38:45,880
Not every gang outcast
manages to gain acceptance.

365
00:38:46,680 --> 00:38:50,000
Hyena gangs are dominated by females.

366
00:38:51,280 --> 00:38:52,640
So like bull elephants,

367
00:38:52,720 --> 00:38:56,120
male hyenas often have to make
their own way in the world.

368
00:38:59,280 --> 00:39:01,200
Without a gang for backup,

369
00:39:01,280 --> 00:39:04,520
a male hyena has to be constantly
on the alert.

370
00:39:11,240 --> 00:39:13,120
(trumpeting)

371
00:39:13,200 --> 00:39:15,080
Exposed and isolated,

372
00:39:15,160 --> 00:39:18,240
he's at the bottom of the grassland
pecking order.

373
00:39:25,600 --> 00:39:28,280
Being alone makes everything harder.

374
00:39:32,600 --> 00:39:35,040
He's looking to join a new clan.

375
00:39:40,800 --> 00:39:42,480
But when you've been kicked out of one,

376
00:39:43,200 --> 00:39:45,120
it's not easy to join another.

377
00:39:55,120 --> 00:39:57,400
Clans won't just let anyone in.

378
00:40:00,800 --> 00:40:04,320
Especially not low-life males
with nothing to offer.

379
00:40:37,320 --> 00:40:38,880
He's not up to snuff,

380
00:40:39,200 --> 00:40:41,920
so it's run or die.

381
00:40:55,760 --> 00:40:59,760
A hyena without a gang
can’t afford to be a fussy eater.

382
00:41:01,920 --> 00:41:04,760
Despite hiding his hurried meal
in the undergrowth...

383
00:41:06,280 --> 00:41:08,240
he can’t escape a rival mob,

384
00:41:12,040 --> 00:41:14,360
a pack of wild dogs.

385
00:41:17,640 --> 00:41:20,120
The smell of carrion has drawn them in.

386
00:41:27,600 --> 00:41:30,760
A whole clan of hyenas would be dangerous,

387
00:41:30,840 --> 00:41:33,800
so an advanced party
susses out the situation.

388
00:41:41,640 --> 00:41:43,520
The hyena is on his own,

389
00:41:43,600 --> 00:41:45,520
making him an easy target.

390
00:41:48,800 --> 00:41:51,040
One on one, the hyena would win,

391
00:41:51,120 --> 00:41:54,960
but he doesn't stand a chance
against a pack this size.

392
00:42:01,680 --> 00:42:05,120
The dogs harass him
until he's forced into the open.

393
00:42:15,360 --> 00:42:17,520
And the gang doesn't stop there!

394
00:42:18,760 --> 00:42:21,520
Wild dogs are nothing if not persistent.

395
00:42:38,560 --> 00:42:42,520
As these top dogs attack the hyena
from all sides...

396
00:42:45,720 --> 00:42:49,400
he has not choice
but to run for his life.

397
00:42:58,040 --> 00:42:59,240
Working together,

398
00:42:59,320 --> 00:43:02,720
this brave band of dogs
is the ultimate proof

399
00:43:02,800 --> 00:43:04,800
that for all Africa's deadliest,

400
00:43:05,400 --> 00:43:08,440
joining forces is the way to survive.

401
